Challenge: Web Application for Serving Guests

Problem statement#

Implement a simple web application for making a list of guests with the following interface:

An input text field to give the guest-name
A summed up list of the guest-names already entered
Also, make it possible to give a name through the url: /add?name=Vera

This code requires the following environment variables to execute:

GOROOT

/usr/local/go

GOPATH

//root/usr/local/go/src

PATH

//root/usr/local/go/src/bin:/usr/local/go/bin://root/usr/local/go/src/bin:/usr/local/go/bin://root/usr/local/go/src/bin:/usr/local/go/bin://root/usr/local/go/src/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
